The principal idea of this volume is to offer a Capita Selecta of unconventional and thought-provoking topics in organometallic chemistry, presented by experts in each field. As intended, this approach leads either to reviews covering a specific uncommon class of organometallic compounds or to overviews which relate uncommon physical properties with various classes of organometallic compounds. The contributions are streamlined thus onto two main axes - unusual properties reflecting structures and bonding situations, on the one hand, and uncommon structural features or structure-reactivity relationships, on the other. Extensive cross-referencing of useful information is provided, making this volume accessible for people working in rather different areas of organometallic chemistry. The synthesis of molecules with 'extreme' properties is a challenge for all those working in organometallic chemistry, irrelevant of theoretical/computational, synthetic or application interests. This book presents case studies at the interface of these overlapping interests. Unusual Structures and Physical Properties in Organometallic Chemistry: * Provides test cases for computational and theoretical models * Presents a challenge for synthetic chemists * Provides ideal show cases for analytical techniques This volume will be an invaluable reference for researchers in organometallic chemistry, computational and theoretical chemistry, NMR and other spectroscopic methods.

Organometallic Syntheses, Volume 3 focuses on the synthesis of compounds containing carbon-metal bonds, including ligands, compounds, chlorides, and derivatives. The selection first elaborates on bis(cyclopentadienyl) organolanthanide and organoyttrium chloride, methyl, and hydride complexes and base stabilized alkali metal halide adducts of bis (pentamethylcyclopentadienyl) lanthanide chlorides. The text then examines cyclopentadienyl metal carbonyl and nitrosyl derivatives, ferrocenylamine, cobalticinium and rhodicinium salts, and alkyl transition metal derivatives. The publication takes a look at transition metal complexes containing organophosphorus ligands, transition metal derivatives containing chalcogen ligands, and coinage metal derivatives. The text also reviews transition metal organometallic compounds, including compounds of group IA, IIA, IIB, and IVA. The selection is a vital reference for researchers interested in the synthesis of compounds containing carbon-metal bonds.

For more than 100 years the Beilstein Handbook has been publishing checked and evaluated data on organic compounds. It has become the major reference book for the chemical and physical properties of organic com pounds. The prediction of these physical properties was the subject of the Beilstein workshop. The ability to predict physical properties is for several reasons of great interest to the Beilstein Institute. It is of primary importance to be able to check the abstracted data for accuracy and to eliminate simple mistakes like typing errors. Presently all the work whether manuscript writing or evaluation of data is carried out manually. This is very time consuming, with the entry of Beilstein into electronic data gathering and publication, the opportunity for computerized consistency checking has become available. Contrary to belief, when one examines the Beilstein Handbook or Chemical Abstracts there is a dearth of chemical information. There are a great many compounds but few are well defined resulting in large gaps in the information available to the chemist. These information gaps could be filled by using algorithmic methods to estimate the properties of interest. An important question to answer is "What is the chemist's reaction to estimated data?" Will he accept it for use, within limits defined by the method, or will it be unacceptable and therefore detrimental for the data base. However if one could partly fill gaps in the data base the increase in the power of the search techniques would be marked.

Traditionally, magnetic materials have been metals or, if inorganic compounds such as oxides, of continuous lattice type. However, in recent years chemists have synthesized increasing numbers of crystalline solids based on molecular building blocks in the form of coordination and organometallic complexes or purely organic molecules, which exhibit spontaneous magnetization. In striking contrast to conventional magnets, these materials are made from solutions close to room temperature rather than by metallurgical or ceramic methods. This book, which originates from contributions to a Discussion Meeting of The Royal Society of London, brings together many of the leading international practitioners in the field, who survey their own recent work and place it in the context of the wider fields of magnetism and supramolecular chemistry. All aspects of molecular-based magnets are addressed, including synthesis, structure-property relations and physical properties. Contents include details of the characterization of the first purely organic ferromagnet, the synthesis of high coercivity materials and a unique description of new materials with Curie temperatures well above ambient. A coherent survey of this rapidly developing field for the more general reader, Metal-Organic and Organic Molecular Magnets will also be welcomed by researchers and lecturers in materials science and inorganic or solid state chemistry.
